OTIS BRIGHAM AND SETH E. BRIGHAM, OF FITCHBURG, MASSACHUSETTS.

ANVIL.

Y 'Y Specification of Letters Patent No. 16,525, dated February 3, 1857.

To all whom it may concern:

Be it known that we, Oris BRIGHAM and SETH E. BRIGr'IAM, of Fitchburg, in the county of Torcester and State of Massachusetts, have invented an Improvement in Blacksmiths Anvils; and we do hereby de- Clare thatthe same is fully described and represented in the following specification and the accompanying drawings, of which- Figure l, denotes a top view Fig. 2, a side elevation, and Fig. 3, a central, vertical and longitudinal section of one of our improved anvils.

The object of our invention, is to enable the anvil to be used in the manufacture of the Snow Ball horse shoe, .or to form the inner edge of a horse shoe as well as its corks beveling so that when the shoe is on a horses foot and snow becomes packed in it, it may easily be thrown out-.or become eject-ed from the shoe by the movements of the feet of the animal when in motion.

In carrying out our invention, we combine with an anvil, A, and on its horn, B, a secondary movable horn, C, which we form with a tapering socket, D, at one end, and with a` lip or projection, E, at its other end as shown in the drawings. In and across the upper surface of this secondary swaging horn we form angular grooves a, b, c, d, having transverse sections suitable to the proper formation of the bevels required to be given to the inner edges of the horse shoe and its corks. This secondary horn, when on the main horn as shown in the drawings, we confine on the said main horn by means of the tapering socket, D, and a bow, G, and its appurtenances as hereinafter described, the bow being placed over and on the secondary horn and against its lip, and made to extend downward toward and under the heel I-I, of the anvil and embrace opposite sides of the said anvil, and pass through a cross bar, I,

as shown in the drawings. The appurtenances of said bow, are the said cross bar, I, screws, e, e, (out in the bow) and screw nuts, f, f, applied to such screws as seen in Fig. l. While the screw nuts are being turned up on the screws, and against the cross bar, I, the bow will be drawn backward, longitudinally as well as downward toward the top surface of the anvil, and so as to impart like motions to the secondary horn, which in consequence of the same and the operation of the socket, I), on the main horn will be drawn closely in and down upon the main horn. The peculiar arrangement of the confining bow and its appurtenances, leaves the top flat surface or face of the anvil free andunobstructed so that the smith while forming the shoe can make use of the said face or top surface as occasion may require.

In using the secondary horn, the smith lays that part of the shoe which he desires to have beveled, in the proper groove of it, and he strikes on the shoe With his hammer, until he has caused it to be driven down into the groove and to take the form thereof. IVhile making any other kind of horse shoe or using the anvil for any other purpose, the secondary horn may be removed from the main horn.

IV e claim- Combining with the anvil, the secondary, movable groovedhorn, and mechanism for confining the latter to the former, the grooved horn being for the purpose as specified.

In testimony whereof, we, have hereunto set our signature this twenty ninth day of November A. D. 1856.
